Abstract
Disclosed is an on-chip tracking sensor for an electromagnetic tracking system, that includes an on-chip sensor coil formed by stacking a plurality of metal layers, in the CMOS technology, and an ultra-low noise Analog Front End (AFE) operably coupled to the on-chip tracking sensor coil. The AFE comprises an instrumentation amplifier with an input referred noise (IRN) less than a predefined value to match up with a pre-defined resistance of the on-chip sensor coil, and a programmable gate amplifier (PGA) serially connected to the instrumentation amplifier for increasing signal strength of an output voltage of the Instrumentation amplifier.
